, Referring.. now particularly toFigs.. 1 to 6,. I0 represents generallythe frameofaltricycle. having aseat Il and a.handle .bar I.2..,. Therear of the frame has aplatfo'r'm. I3 to whichthere. is connectedatransversely extending axle -l4 which may be rigidly .secured theretoby welding.Y This axle. carriesbn the. opposite. ends thereofopposingly,arrangedbrakedrumsAv l5 and i6 having respectively external.braking surfaces and over which there extends respectively brake. bandsl1 and i8, These bands. are rigidly anchored'v respectively totheplatform by brackets. I9 and 2l. A double crankshaftv Z2 is`iournalled in bearing elements 23. and 24 and its respective crank arms25. and.2.6 are xed toA the Vfree. ends of. the bands I'I.v and I8 sothat asthe shaft 22. is. turned, the bandswill be-tightenedor loosened'.Centrally-.lot thershat22 is, a. bent arm portion .21 which is connectedby alink. 28.. to a bell crank 29 that is pivoted at. 31. on the bicycleframe. l0 at a locationbeneaththe seat I l.

extends for connection with a front. Wheel yoke in'which the. frontlarge drive wheel 3lY is journalled.

Av pedal crank. isA xedto the wheel. 31 and haspedals 39 andft on-.theopposite ends. thereof. i Av pull armby which. the mother can..pu1l thetricycle is. indicated at 42and has forked portions 'extendingon theopposite.. sides of the depending yoke .36 and these.. portions .arerespectively pivotallyconnected thereto, by pins 43.4 and 4.4.

The forward vertical sleeve 3.4 ofY the frame. lll has a bell crank. 45.pivotally connected thereto, one end ofwhich is connected by 'la link46. with the bell crank 2S. The'link 4T is connected between the bellcrank and is pivotally connected to an extension of the draw pull arm orbar 42 by a thumb screw 48. The pull bar 42 has a long tension spring 5|which is connected between the platform I3 at the rear end thereof asshown of one of the forked extensions.

rin Fig. 4 and the depending link 28, as indicated at 52. This springtends to hold the crank shaft turned to normally effect braking actionupon the two wheel brakes. When the draw pull bar 42 is lifted and isfastened to the handle bars as by a hook 53 the spring 5l will tend tohold the brake bands in a position to effect braking action upon thewheels 32 and 33. As the pull handle 42 is released from the handle barsby a release of the hook 53 and pivoted downwardly to a dotted lineposition as shown in Fig. 1, the brake bands I1 and I8 will beautomatically released so that the wheels will be free to permit easypulling of the tricycle over the ground.

In Figs. '1 and 8 there is shown a modified form of the inventionwherein the draw pull handle 42 can serve to separate the pedals on thefront wheel and release them for use as a foot rest for the child.According to this form of the invention separable pedal crank arms 55and 55 having s respectively foot pedals 51 and 58 are journalled on thelower end of the forked member 35. The arm 55 has an enlarged diameterportion 5| on which wheel hub 62 is journalled. This portion has a slot63 in the end thereof for receiving a pin 54 in the hub. The arm 56 hasan enlarged end 55 for receiving pin 56 in its slct 51. A spring 68 isconnected between the ends of the arms 55 and 56 and normally urge theends of the arms together with the pins 54 and 55 lying in the slots 63and 61 respectively.

The draw pull arm 1l is pivotally connected to the fork 36 by portionsof the arm extending downwardly on the opposite sides of the fork andfixed to the fork by a pin projecting from the arm draw pull arm iskraised, however, the cam pro- L jecticns 12 will be removed from theforrnation 13 so that the crank arms 55 and 55 will be drawn inwardly bythe spring 68 to lock the respective cranks with the pins 64 and 55 onthe hub 62 of the wheel 31. The link 41 is connected to this draw pullarm 1l by means of a thumb screw 48 in the same manner as abovedescribed.

If it is desired to remove the draw bar 42, the same can be easily doneby separating the forked formation thereof and the link 41 from the endThe thumb screw 48 then can be fastened into a threaded released. Itwill be seen that with the combina-y tion that the drive pedals can beautomatically adjusted according to the form of the invention shown inFigs. '7 and 8 so as to serve as a foot rest for the child while thetricycle is being pulled and when the draw bar is raised tc a raisedposition, the foot pedals will then become engaged with the drive wheel,and the child can drive the tricycle through the means of the drivewheel. This is also effected when the draw bar is removed from thetricycle and the link 41 raised to an elevated position upon the link 46with the thumb screw 4B in the threaded hole 15.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be Within the spirit and scope ofthe. present invention as defined by the appended claims.-

What is claimed is:

1. In combination, a tricycle having a frame, a platform connected to`the rear of the frame, an axle connected to the platform, brake devicescarried by the axle, crank and linkage means connected to the brakedevices and extending forwardly over the frame of the tricycle andhaving elements thereon pivotally connected to the frame, a steeringwheel fork pivoted upon the frame, a drive wheel journalled upon thefork, handle means, pedal crank means connected to the drive wheel, adraw pull bar pivotally connected to the drive wheel fork, said linkagemeans pivotally connected to the draw pull bar to be operated by thesame, said linkage operable by the pull bar when the pull bar is liftedto actuate the pull devices and when the pull bar is lowered to free thedevices and allow free rotation of the rear wheels, and said crankpedals on the drive wheel comprising separable pedal crank arms, springmeans urging said arms toward one another, drive pin connections forreleasably connecting said arms with the drive wheel hub and means uponthe draw pull arm and engageable with the pedal crank arms to releasethe pedal crank arms upon the draw pull handle being lowered to apulling position.

2. In combination, a tricycle, brake means mounted on` said tricycle andoperable between braking and released positions thereof, a draw pull barpivotally connected to the tricycle at the forward end thereof, saidbrake means connected to the draw pull bar and operable thereby as thedraw pull bar is moved up and down, a drive wheel connected to theforward end of the tricycle and separable pedal arms extending into thedrive wheel and axially adjustable relative to each other, meansextending between the wheel and the separable pedal arms to releasablyholdv the respective arms in driving relationship with the wheel andmeans extending between the draw pull bar and the separable pedal armsto release the pedal arms from the wheel as the draw pull bar is loweredfrom the tricycle.
